Description

Technical Field

[0001] This utility model relates to the field of grease trap technology, and in particular to an environmentally friendly, anti-clogging grease trap. Background Technology

[0002] An oil separator is a device that uses the density difference between oil and water to separate oil and water. It is mainly used for the pretreatment of oily wastewater. When oily wastewater enters the oil separator, the oil will float to the surface due to the density difference between oil and water. The oil separator slows down the water flow by setting baffles or packing with different structures, allowing the oil droplets enough time to float to the surface, thereby achieving oil-water separation. It is widely used in catering, food processing, hotels, hospitals, car washes and other places that generate oily wastewater.

[0003] A search revealed Chinese Patent Publication No. CN222456326U, which discloses a commercial kitchen grease trap. The grease trap includes an anti-clogging component. During operation, a filter tray is mounted on a vibrating mounting plate of the anti-clogging component. Kitchen wastewater enters the grease trap through an inlet, and a vibration motor is controlled by a switch. The vibrating mounting plate is mounted on top of a mounting baffle via a support spring and a telescopic guide rod. The vibration motor and spring then cause the mounting plate and filter tray to vibrate up and down, effectively reducing the risk of clogging.

[0004] In actual use, the aforementioned grease traps cause wastewater to enter the tank and then be filtered in the filter cake tank. Once too much impurity accumulates in the filter cake tank and covers the filter screen, even with a vibration device, it is difficult to ensure smooth water flow. At the same time, the grease mixed in the water will also mix with the filtered impurities when it reaches the filter cake tank, forming a viscous mixture. This greatly increases the risk of blockage in the filter cake tank. Therefore, an environmentally friendly, anti-clogging grease trap is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an environmentally friendly, anti-clogging grease trap, which aims to improve the problem in the prior art that "if there are many impurities mixed in the sewage, it will quickly cause blockage inside the filter tank, and the impurities will mix with the grease to form a viscous mixture".

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 This utility model provides an embodiment of an environmentally friendly, anti-clogging grease trap, comprising a tank body 1. An inlet pipe 2 is fixedly connected to the left side surface of the tank body 1, allowing wastewater to enter the tank body 1 through the inlet pipe 2. A drain pipe 3 is fixedly connected to the right side surface of the tank body 1, allowing the wastewater to be discharged through the drain pipe 3 after grease trapping treatment inside the tank body 1. A cleaning channel 4 is installed on the upper surface of the tank body 1, and a cover is provided above the cleaning channel 4, allowing workers to clean the oil and wastewater inside the tank body 1 through the cleaning channel 4. The wastewater is cleaned up. An oil separator 5 is fixedly connected to the top surface of the tank body 1. A gap is left between the bottom surface of the oil separator 5 and the bottom surface of the tank body 1. When the wastewater reaches the left side of the oil separator 5, the oil mixed in the wastewater has a lower density and will float on the surface of the liquid. At this time, the water flow is in the lower layer and can flow to the right side of the oil separator 5 through the gap at the bottom of the oil separator 5, so that the oil and water flow are separated. The water flow that reaches the right side of the oil separator 5 can be discharged through the drain pipe 3. The above structure is a prior art in this field and will not be described in detail here.

[0034] Reference Figures 3-5 An inclined plate 6 is fixedly connected to the bottom surface of the tank body 1. The inclined plate 6 can divide the space on the left side of the oil separator 5. The left side of the inclined plate 6 is a sludge storage space, and the right side is an oil-water separation space. An inclined filter screen 7 is fixedly connected to the upper surface of the inclined plate 6. The upper end of the inclined filter screen 7 is inclined to the right. When water flows onto the inclined filter screen 7, the inclined filter screen 7 can filter the impurities mixed in the water flow, while the wastewater can continue to flow downward through the inclined filter screen 7 to the left side of the oil separator 5. A limiting plate 8 is fixedly connected above the inclined filter screen 7. The upper surface of the limiting plate 8 is fixedly connected to the top surface of the tank body 1. Positioning plate 8 can fix and limit the top of the inclined filter screen 7, improving the stability of the inclined filter screen 7. The front and rear sides of the inclined plate 6, the inclined filter screen 7 and the limiting plate 8 are fixedly connected to the inner wall surfaces of the front and rear sides of the pool body 1 respectively. A support rod 9 is fixedly connected inside the pool body 1. The support rod 9 is located at the bend position where the inclined plate 6 and the inclined filter screen 7 are connected. At the same time, the surface of the support rod 9 is in contact with the outer wall of the inclined plate 6 and the inclined filter screen 7, which can support and limit the bend position, improve the connection stability at the bend position and avoid the risk of the inclined filter screen 7 breaking and being damaged under long-term water flow impact.

[0035] A slag discharge port 10 is provided on the left side surface of the tank body 1. When the water flows to the inclined filter screen 7 and is filtered, the wastewater continues to flow downward through the inclined filter screen 7, while the filtered impurities can slide down to the left side of the inclined surface of the inclined filter screen 7 and then reach the left side of the inclined plate 6 for storage, thus greatly reducing the risk of the inclined filter screen 7 being blocked. The staff can quickly clean the filtered impurities through the slag discharge port 10. A sealing component 11 is provided on the left side of the slag discharge port 10. The sealing component 11 includes a sealing plate 111, which is located on the left side of the tank body 1. A sealing rubber gasket 112 is fixedly connected to the right side surface of the sealing plate 111. The right side surface of the sealing rubber gasket 112 is in contact with the left side surface of the pool body 1. The sealing rubber gasket 112 can seal and fill the gap between the sealing plate 111 and the edge of the slag discharge port 10, thereby improving the stability of the seal. Side plates 113 are fixedly connected to both the front and rear sides of the pool body 1. The sealing plate 111 is detachably connected to the side plate 113 by bolts. When the operator tightens the bolts, the side plate 113 can be moved to the left side surface of the pool body 1 and pressed tightly, thereby squeezing the sealing rubber gasket 112, so that the sealing plate 111 is kept in a stable position, and the sealing rubber gasket 112 is squeezed and deformed, further improving the sealing effect.

[0036] Reference Figure 2 and Figure 6 A connecting pipe 12 is fixedly connected to the inner left side of the pool body 1. The connecting pipe 12 is interconnected with the inlet pipe 2, allowing sewage to enter the connecting pipe 12 through the inlet pipe 2. A diversion hood 13 is fixedly connected to the right end of the connecting pipe 12. The diversion hood 13 has a triangular structure, with the left side smaller than the right. A fixing rod 14 is fixedly connected to the left side of the diversion hood 13, with the left end of the fixing rod 14 fixedly connected to the inner left side of the pool body 1. The diversion hood 13 is fixedly connected to the inside of the pool body 1 via the fixing rod 14, which improves the stability of the diversion hood 13. Several triangular diversion blocks 15 are fixedly connected inside the diversion hood 13. The tip of the flow block 15 faces to the left, and its upper and lower surfaces are respectively attached to and fixedly connected to the inner walls of the upper and lower sides of the diversion hood 13. The triangular diversion block 15 can continuously divert the flow of sewage entering the diversion hood 13 through the connecting pipe 12, so that the sewage can flow fully through the right opening of the diversion hood 13 to the inclined filter screen 7, thereby increasing the contact area between the sewage and the inclined filter screen 7. This avoids the situation where, after the sewage enters the tank 1 through the inlet pipe 2, it can only contact a fixed part of the inclined filter screen 7 due to the fixed flow direction, which would greatly increase the risk of blockage and affect the service life of the inclined filter screen 7.

[0037] Working principle: Wastewater flows into connecting pipe 12 through inlet pipe 2. When it reaches the diversion hood 13, it will be diverted along the inclined surfaces on both sides of the triangular diversion block 15. It will flow evenly to the inclined filter screen 7 through the right opening of the diversion hood 13, increasing the contact area between the wastewater and the filter screen and avoiding local blockage. After diversion, the wastewater flows through the inclined filter screen 7, and impurities are intercepted by the filter screen. At this time, the impurities will slide to the left side of the inclined surface of the inclined filter screen 7 to the slag storage space on the left side of the inclined plate 6, thereby reducing the residence time of impurities on the inclined filter screen 7 and reducing the risk of blockage. At the same time, it can prevent floating oil from coming into contact with impurities and mixing to form a viscous mixture that adheres to the tank body 1 and causes blockage over time.

[0038] Wastewater passing through the inclined filter 7 continues to flow downwards, reaching the oil-water separation space on the left side of the oil separator 5. Since the density of grease is less than that of water, grease, being less dense, floats on the surface of the water, while water, being more dense, lies at the bottom. The lower layer of water flows to the right through the gap at the bottom of the oil separator 5 and is eventually discharged from the drain pipe 3. The upper layer of grease is blocked by the oil separator 5 and remains on the left side, which can be periodically removed by opening the cleaning channel 4. During this process, the inclined plate 6 divides the left side space of the tank 1 into a sludge storage area and an oil-water separation area, preventing impurities from interfering with the oil-water separation.

[0039] When the impurities pushed out by the left side of the inclined plate 6 need to be cleaned, the bolts can be turned directly to release the limiting fixation of the sealing plate 111. Then the sealing plate 111 can be removed and cleaned through the slag discharge port 10. The structure is simple, the operation is convenient, and the practicality is strong.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
